Restructure legacy backups, remove pe_accel, fix DMA self-routing

Browse Source 
- Move builtin_legacy/ → legacy/builtin/ (cleaner structure)
- Move pe_accel_legacy/ → legacy/pe_accel/
- Remove custom/pe_accel/ (replaced by new builtin)
- Remove pe_scheduler_v2 from components.yaml
- Switch topology.yaml to pe_scheduler_v1 (new builtin)
- Fix PE_DMA self-routing: handle consecutive DMA_READ stages
  (same component consecutive stages processed in-place, not via port)

382 tests passing.
